This invention relates to the treatment and use of city refuse for thefilling-in of mud flats.

The refuse collected in most cities comprises a large proportion of oldpaper, cardboard boxes,

f 5 and the like, as well as food refuse and other fermentableingredients and other waste products,

and the disposal thereof involves considerable ex-Y pense to manycities.

Many mud ats, due to one cause or another,

V give off very disagreeable odors, this being sometimes due todeposition of sewage by receding tides in the case of tidelands, so thatland,v

Another object of my invention is to make useful disposition of cityrefuse.

Another object of my invention is to use city refuse in such manner thatit will become an asset of value to the city which otherwise had theproblem of disposing thereof. i

Another object of my invention such manner that it will convert aliability into a valuable asset.

Another object of my invention is to use such refuse for filling in suchmud flats.

Another object of my invention is to do away with the odors arising fromsuch mud ats.

is to use it in municipal Another object of my invention is to lill inand 'to make of suchmud flats good land useful for ordinary municipalpurposes such, for example, as building lots, streets, parks, and thelike.

Another object of my invention is to fill in such mud flats with suchmunicipal refuse in such 40,manner that it will not only be odorless,but free of rats, flies and vermin in general.

Other objects of my invention will become apparent on reading theappended specification, taken in connection with the appended drawing gwhich lforms a part thereof.

The figure of the drawing is a vertical sectional view of a completedfill made according to my invention.

In some cities no separate storage and collection are made of drygarbage and wet garbage, but all garbage is collected merely as oneitem. According to my invention, such garbage is thoroughly soaked withwater, preferably salt water if available, and a layer thereof aboutfour feet vthick is laid at low tide on the mud, this being rolled witha'twelve-ton roller to compress it, thereby reducing it rto thickness ofabout two feet. The refuse may be wetted with the water before ,or afterspreading in layers, as may be desired,

but I generally prefer to wet it before spreading. 30

On the drawing the mud is illustrated at 10 andthe compressed refuselayer at 11. This layer is'then covered with a layer of oil, preferablyasphaltic oil, although any oil may be used which will not impart adisagreeable odor when the 65 work is completed and which will tend torepel rats, flies and other vermin. A layer of earth of about six inchesto one foot thick is placed thereover, and this is rolled, preferablywith a twelve-t0n roller, to produce the layer 12.

Thereupon, the above set of steps is repeated until the desired heightis obtained; that is, a layer of refuse 13 is providedon the layer 12,and layer 13 being similar to the layer 11 and being treated in the samemanner by wetting, rolling and oil application, and a layer 14 isprovided on the layer 13,y this layer 14 being similar to and producedin the same manner as the layer l2. I have illustrated on the drawingonly one repetition of such steps, but the number thereof will bedetermined by the depth of ll desired.

On top of the whole a thickness of earth is placed which will yield athickness 15 of about two feet when solidly compacted, it beingcompacted by rolling, preferably with a twelve-ton roller. Thereupon itis rolled with a twelve-'ton roller having spikes about six inches longin the wheels thereof, and a surface coat of hot oil is then appliedwhich is allowed to soak in for twenty-four hours; whereupon it isrolled with a twelve-ton roller Without spikes which seals the topsurface.

The method as described above may be applied to slimy mud flats withoutcausing mud waves as does a heavy rock fill. r I'he salt water is usedfor the purpose of softening the paper, cardboard, boxes and the likewhich gives a greater tendency thereto to be compressed and compacted bythe roller. Fresh water may be used in place of salt water, but I prefersalt water when available. v

Fills on mud flats made according to my method will carry a sixty-tonsteam shovel or other object without any indentation of the surface and,in fact, they will carry a locomotive with a train of freight carsloaded Ato full capacity. A seven-ton truck loaded with seven tons ofearth can travel over the surface at a rate of twenty miles an hour.

My invention provides a way for advantageously disposing of city refuseas a Whole, thereby avoiding the requirement of separating it into orkeeping separated the dry and Wet components, so that it results insimplifying the collection ofthe refuse in that both kinds can be storedby the householder in one container and removed in the same conveyance.

in some cities the dry garbage is collected separately from the Wetgarbage, that is, paper, cardboard, ashes and other solid dry refuse iscollected separately from the Wet garbage which may contain refuse suchas fatty and other food matter, melon rinds, fruit and vegetable pulp`or skins, and other like material. However, if certain municipalitiesshould desire to collect the Wet refuse and the dry refuseseparatelynboth the Wet and the dry may be used according to myinvention or, if desired, only the dry refuse may be so used.

Ix/iy invention has an additional advantage for use in districts Wherethere are unimproved and Luidesired hills, since it provides fordisposal of `the earth obtained in grading such hills inasf posing ofmunicipal refuse containing Vmaterial made of paper pulp, whichcomprises providing on said mudiiats a substantially four-foot-thicklayer-of said refuse soaked with salt water, rolling saidfour-foot-thick layer with a twelve-ton roller to a thickness of tvvofeet, covering said resulting layer with hot asphaltic oil, coveringsaid oiled layer with earth to a thickness of from onen half foot to oneroot, then rolling with a twelveton roller, building up on saidlaminated nil sol iprovided by repeating the above mentioned sequence ofsteps until the desired thickness of fill attained, locating on topthereof a twofootthick layer of solidly compacted earth, rolling thesurface thereof with a twelve-ton roller having six-inch spikes,applying hot oil to the spiked surface and permitting the same to soakin for twenty-four hours, and then rolling the surface with a twe1ve-tonsmooth roller. g

2. rThe method of filling in mud flats and disposing of municipal refusecontaining material made of paper pulp, which comprises providing onsaid mud ats a layer ci said refuse soaked with water, compressing saidlayer, covering the resulting compressed layer with oil, covering saidoiled layer with earth, and compressing said earth.

3. The method of filling in mud flats and disposing of municipal refusecontaining material made of paper pulp, which comprises providing onsaid mud flats a layer of said refuse soaked with Water, compressingsaid layer to about onehalf its thickness, covering said resulting layerwith oil, covering said oiledlayer With, earth and compressing saidearth, building up on saidlaminated fill so providediby repeating theabove^mentioned sequence oi steps until the desired thick` ness of fillis attained, then locatingontop'there-- of a layer of solidly compactedearth, perforat the surface of said topmost layer, applying cil to theperforated surface and permitting the sarnevto soak in, and thensmoothingoverthe surface.

4. The method of filling in mud flats and disposing of municipal refusecontaining material rmade of paper pulp, which comprises providingquence of steps until the desired thickness of iill.

is attainedgthen locating on top` thereof Y a layer of solidly compactedearth, rolling andperfo'rate ing the surface of said topinost layer,rapplying oil to the perfcratedsurface and permitting the' same to soakin for twentyafour hours', and then Q rolling the surface.
